Abstract
INTRODUCTION Traumatic event exposure is a risk factor for the development and maintenance of psychopathology. Social-affective responses to trauma exposure (e.g. shame, guilt, revenge, social alienation) could moderate this relationship, but little is known about their relevance for different types of psychopathology. Moreover, the interplay of different social-affective responses to trauma exposure in predicting psychopathology is poorly understood. METHODS In a sample of N = 1321 trauma-exposed German soldiers, we examined cross-sectional associations of trauma-related social alienation, revenge, guilt and shame with depressive disorder, alcohol use disorder, posttraumatic stress disorder and dimensional measures of depression and anxiety. Latent class analysis was conducted to identify possible patterns of social-affective responses to trauma exposure, and their relation to psychopathology. RESULTS All social-affective responses to trauma exposure predicted current posttraumatic stress disorder, depressive disorder, alcohol use disorder and higher depressive and anxiety symptoms. Three latent classes fitted the data best, reflecting groups with (1) low, (2) moderate and (3) high risk for social-affective responses to trauma exposure. The low-risk group demonstrated the lowest expressions on all psychopathology measures. CONCLUSIONS Trauma-related social alienation, shame, guilt, and revenge are characteristic of individuals with posttraumatic stress disorder, depressive disorder, alcohol use disorder, and with higher anxiety and depressive symptoms. There was little evidence for distinctive patterns of social-affective responses to trauma exposure despite variation in the overall proneness to show social-affective responses. Social-affective responses to trauma exposure could represent promising treatment targets for both cognitive and emotion-focused interventions.

Examining bidirectional associations between perceived social support and psychological symptoms in the context of stressful event exposure: a prospective, longitudinal study. BMC Psychiatry 2022; 22:736. [PMID: 36443716 PMCID: PMC9703701 DOI: 10.1186/s12888-022-04386-0] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/04/2022] [Accepted: 11/11/2022] [Indexed: 11/29/2022] Open
Abstract
BACKGROUND After stressful event exposure, higher perceived social support is a well-established correlate of decreased risk for psychological symptoms, including depressive, anxiety and posttraumatic stress (PTS) symptoms. However, longitudinal data on the direction of this association and the stability of perceived social support are scarce and have yielded mixed results, with a particular lack of prospective studies. We aimed to investigate changes in perceived social support and bidirectional associations between perceived social support and psychological symptoms in a prospective, longitudinal study. METHODS A sample of German soldiers was assessed before and after deployment to Afghanistan. Group-based trajectory modelling was used to investigate the stability of perceived social support and to identify possible distinguishable trajectories of perceived social support. Bidirectional associations between perceived social support (general and workplace) and psychological symptoms (depressive, anxiety and PTS) were examined using gamma regressions. RESULTS Average levels of perceived general social support did not change, while perceived workplace social support increased slightly (t(344) = 5.51, p < .001). There were no distinguishable trajectories of perceived social support. Higher perceived general (Mean ratio (MR) = 0.84, 95% CI = [0.74, 0.95]) and workplace social support (MR = 0.82, 95% CI = [0.72, 0.92]) predicted lower depressive symptoms, but not anxiety or PTS symptoms. Only higher PTS (MR = 0.95, 95% CI = [0.91, 0.99]) and higher depressive symptoms (MR = 0.96, 95% CI = [0.93, 0.99]) predicted lower perceived general social support. CONCLUSIONS Perceived social support can remain relatively stable under exposure to environmental stressors such as military deployment. Higher perceived social support could protect against depressive symptoms via a stress-buffering mechanism, while support may need to be more tailored to individual needs for a protection against PTS symptoms. Individuals with elevated depressive and PTS symptoms might have impaired abilities or opportunities to access social support after stressful event exposure. Future studies could investigate distressing social emotions and associated maladaptive social cognitions as possible mechanisms in the association between symptoms and lower perceived social support. Especially with respect to PTS symptoms, future studies could focus on conditions that enable individuals to benefit from social support.

A proof-of-concept study in German soldiers before and after deployment to Afghanistan. BMC Psychol 2021; 9:198. [PMID: 34924023 PMCID: PMC8686273 DOI: 10.1186/s40359-021-00696-2] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/11/2021] [Accepted: 11/25/2021] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND AND OBJECTIVES Disorder-specific forms of Repetitive Negative Thinking (RNT) are associated with multiple diagnostic categories, indicating a transdiagnostic nature. Few studies examined content-independent RNT processes across groups of diagnosed mental disorders. Moreover, theory describes RNT processes as critically involved in the etiology of mental disorders, empirical evidence however is scarce. We first tested the transdiagnostic nature by examining levels of RNT across groups of internalizing and externalizing mental disorders compared to healthy individuals and explored RNT levels in a comorbid disorder-group. Second, we examined whether RNT predicts incident psychopathology. METHODS In a sample of German soldiers (n = 425) scheduled for deployment in Afghanistan, we compared RNT levels between diagnosed groups with alcohol use disorders, anxiety disorders and healthy individuals cross-sectionally. Exploratory analyses were conducted comparing a comorbid disorder-group to healthy individuals and to both single-disorder-groups. Longitudinally, we examined the predictive value of pre-deployment RNT levels for incident psychopathology after deployment (n = 167). RNT was measured using the Perseverative Thinking Questionnaire (PTQ), DSM-IV diagnoses were assessed using the standardized Composite International Diagnostic Interview (CIDI). RESULTS Cross-sectional comparisons revealed that soldiers with alcohol use disorders and anxiety disorders showed significantly higher degrees of RNT compared to healthy soldiers. RNT levels in those with comorbid disorders were significantly higher compared to healthy soldiers but also compared to both single-disorder-groups. Longitudinal analyses revealed that higher levels of RNT prior to deployment were associated with a higher risk to have any incidental mental disorder after deployment. This however is only attributable to individuals with a PTQ score above a cut-off of 15. CONCLUSIONS Findings provide evidence for RNT as a transdiagnostic correlate and a vulnerability factor for the development of mental disorders.

Abstract
Severe disorders of emotion regulation, e.g. in the context of mental illnesses, such as borderline disorders, attention deficit hyperactivity disorder (ADHD) and complex posttraumatic stress disorder (PTSD), often begin in childhood and adolescence and influence the psychosocial development of those affected, often into adulthood. Professional treatment therefore often requires longer term planning, if possible from a single source. The sectorized structure of the current psychiatric healthcare system, however, makes this process more difficult or is even a hindrance and promotes high hospitalization rates and chronification. The concept of the Adolescents Center for Disorders of Emotion Regulation at the Central Institute of Mental Health functions as a model concept for long-term, cross-sectoral treatment structures. A constant treatment team from child, adolescent and adult psychiatry and psychotherapy provides evidence-based psychotherapy according to the guidelines of dialectical behavior therapy (DBT) for those affected between the ages of 16 and 24 years. Conceptually, inpatient, day care and staged outpatient treatment modules complement each other in order to not only provide psychotherapy to the young patients in this important phase of life but also to accompany and support them in completing school and training, in partnership and independent living.

Abstract
PURPOSE The purpose of this study is to identify key risk factors that could negatively affect public health emergency responders' health and wellbeing. We seek to use this information to provide recommendations and strategies to mitigate such risks. DESIGN/METHODOLOGY/APPROACH A narrative review of the peer-reviewed literature on wellbeing of military personnel and other responders was conducted. Data was grouped and categorized according to overarching domains. FINDINGS Factors associated with wellbeing were categorized into 5 domains: (1) demographics; (2) mental health concerns; (3) social networks; (4) work environment; and (5) postdeployment life. The strategies identified to promote wellbeing included mental health assessments, preparedness trainings, debriefs in the field, postdeployment debriefs, resources in the field, and further postdeployment decompression strategies. ORIGINALITY/VALUE This study provides a unique understanding of the risk factors associated with poor health and wellbeing outcomes in public health emergency response work by extending the body of knowledge that focuses on other types of emergency and military response.

Abstract
Alcohol misuse is a common sequela of traumatic event experiences causing considerable morbidity and mortality. Although biological stress indicators have been identified as useful risk markers for the development of trauma-related disorders, no such biological indicators exist for the risk of increased alcohol use after trauma exposure. This is the first study to prospectively investigate the predictive value of long-term cortisol levels and acute stress reactivity for the risk of increased alcohol use following traumatic events. Male soldiers were examined before and 12 months following deployment using a standardized diagnostic interview. We analyzed the moderating role of baseline hair cortisol concentrations (HCCs, n = 153) as well as baseline salivary cortisol and alpha-amylase stress reactivity in response to a laboratory stressor (n = 145) in the association between new-onset traumatic events (according to the DSM-IV A1 criterion) and subsequent daily alcohol use. No main effects of pre-traumatic HCC or salivary stress markers on subsequent change in alcohol use were observed. However, we found that with decreasing HCC, the number of new-onset traumatic events was more strongly associated with subsequent alcohol use independent from changes in posttraumatic stress disorder symptoms. No such relation was seen for the acute stress reactivity data. Taken together, this study provides first evidence suggesting that individual differences in long-term cortisol regulation are involved in the association between traumatic experiences and subsequent alcohol use. HCC may thus serve as a potential target in the early identification of individuals vulnerable for increased alcohol use following traumatic events.

Abstract
OBJECTIVE Post-traumatic stress disorder is common among North Korean refugees who have fled their country for economic, financial and humanitarian reasons. Co-morbid depression and anxiety are also common among North Korean refugees, due to the difficulties they have faced within their country and during their escape journey. Depression and anxiety complicate treatment for post-traumatic stress disorder, and lead to poorer outcomes. Thus, the aim of the present study was to provide a meta-analysis of studies investigating post-traumatic stress disorder, depression, and anxiety among North Korean refugees. METHODS Selected articles were published in English, and included measures of post-traumatic stress, and/or depression and anxiety. 10 studies were included in the depression meta-analysis, and 6 in the anxiety meta-analysis. RESULTS A random-effects model revealed strong, significant associations between post-traumatic stress and depression, r=0.63, 95% CI (0.51, 0.72), p<0.001, z=8.33, and anxiety, r=0.51, 95% CI (0.36, 0.63), p<0.001, z=6.07. The relationships between post-traumatic stress, depression and anxiety were higher among adults and those with more than five years outside of North Korea. CONCLUSION Depression appears to be an important treatment focus for North Korean refugees with post-traumatic stress.

Abstract
AIMS Provision and need for mental health services among military personnel are a major concern across nations. Two recent comparisons suggest higher rates of mental disorders in US and UK military personnel compared with civilians. However, these findings may not apply to other nations. Previous studies have focused on the overall effects of military service rather than the separate effects of military service and deployment. This study compared German military personnel with and without a history of deployment to sociodemographically matched civilians regarding prevalence and severity of 12-month DSM-IV mental disorders. METHOD 1439 deployed soldiers (DS), 779 never deployed soldiers (NS) and 1023 civilians were assessed with an adapted version of the Munich Composite International Diagnostic interview across the same timeframe. Data were weighted using propensity score methodology to assure comparability of the three samples. RESULTS Compared with adjusted civilians, the prevalence of any 12-month disorder was lower in NS (OR: 0.7, 95% CI: 0.5-0.99) and did not differ in DS. Significant differences between military personnel and civilians regarding prevalence and severity of individual diagnoses were only apparent for alcohol (DS: OR: 0.3, 95% CI: 0.1-0.6; NS: OR: 0.2, 95% CI: 0.1-0.6) and nicotine dependence (DS: OR: 0.5, 95% CI: 0.3-0.6; NS: OR: 0.5, 95% CI: 0.3-0.7) with lower values in both military samples. Elevated rates of panic/agoraphobia (OR: 2.7, 95% CI: 1.4-5.3) and posttraumatic stress disorder (OR: 3.2, 95% CI: 1.3-8.0) were observed in DS with high combat exposure compared with civilians. CONCLUSIONS Rates and severity of mental disorders in the German military are comparable with civilians for internalising and lower for substance use disorders. A higher risk of some disorders is reduced to DS with high combat exposure. This finding has implications for mental health service provision and the need for targeted interventions. Differences to previous US and UK studies that suggest an overall higher prevalence in military personnel might result from divergent study methods, deployment characteristics, military structures and occupational factors. Some of these factors might yield valuable targets to improve military mental health.

Abstract
China Mental Health Survey (CMHS), which was carried out from July 2013 to March 2015, was the first national representative community survey of mental disorders and mental health services in China using computer-assisted personal interview (CAPI). Face-to-face interviews were finished in the homes of respondents who were selected from a nationally representative multi-stage disproportionate stratified sampling procedure. Sample selection was integrated with the National Chronic Disease and Risk Factor Surveillance Survey administered by the National Centre for Chronic and Non-communicable Disease Control and Prevention in 2013, which made it possible to obtain both physical and mental health information of Chinese community population. One-stage design of data collection was used in the CMHS to obtain the information of mental disorders, including mood disorders, anxiety disorders, and substance use disorders, while two-stage design was applied for schizophrenia and other psychotic disorders, and dementia. A total of 28,140 respondents finished the survey with 72.9% of the overall response rate. This paper describes the survey mode, fieldwork organization, procedures, and the sample design and weighting of the CMHS. Detailed information is presented on the establishment of a new payment scheme for interviewers, results of the quality control in both stages, and evaluations to the weighting.

Abstract
BACKGROUND Attentional bias (AB) to threat is thought to play a key role in the development and maintenance of posttraumatic stress symptomatology (PTS). Empirical evidence though is inconsistent. Some studies report associations between AB towards, threat and PTS; other studies report associations between AB away from threat and PTS; yet other studies fail to find any association. We propose that prospective-longitudinal study of AB as a dynamic process, expressed from moment to moment in time, may help to understand these mixed findings and the role of AB in PTS. METHODS We tested cross-sectional and prospective-longitudinal associations between AB and PTS among German soldiers from pre- to post-deployment in Afghanistan (n = 144). AB to threat and positive emotion stimuli (angry/happy faces) was measured using the dot-probe task. PTS was assessed by the PTSD Checklist. The number of traumatic experiences was assessed using CIDI-traumatic experience lists for military. RESULTS We found that AB dynamics (i.e., towards, away, temporal variability) at pre- and post-deployment, with respect to angry and happy faces, predicted higher levels of PTS after deployment as a function of number of intermediate traumatic experiences. Traditional aggregated mean bias scores did not similarly prospectively predict PTS post deployment. CONCLUSIONS Findings indicate that AB to emotionally arousing stimuli may play an important function in the development and maintenance of PTS. We argue that mixed and null findings appear to be due to failure to model the within-subject temporal variability in AB expression. Theoretical, empirical, and clinical implications of these findings are discussed.

Abstract
BACKGROUND Volunteering in international military missions has been scrutinized for its effects on mental health. Different kinds of exposures to traumatic events are associated with a variety of mental disorders, mainly heightened rates of post-traumatic stress disorder (PTSD) and alcohol abuse. AIMS Based on the literature we discuss risk and protective factors concerning the psychological well-being of soldiers attending to international military operations. METHODS A systematic literature search was carried out using relevant search terms to identify the articles for this review. RESULTS AND CONCLUSIONS The ability to recognize and treat acute stress reactions during deployments is important. Post-deployment psychosocial support and services have a role in lowering barriers to care, diminishing stigma and also in recognizing individuals who suffer from psychological distress or psychiatric symptoms, to connect them with appropriate care. Further investigation of gender differences and the role of stigmatization is warranted. Most of those participating in international military operations are repatriated without problems, but repeated exposure to combat situations and other stressors may affect mental health in various ways. Stigmatization is still a barrier to care.

Abstract
BACKGROUND It is unclear how many children and adolescents develop post-traumatic stress disorder (PTSD) after trauma. AIMS To determine the incidence of PTSD in trauma-exposed children and adolescents as assessed with well-established diagnostic interviews and to examine potential moderators of the estimate. METHOD A systematic literature search identified 72 peer-reviewed articles on 43 independent samples (n = 3563). Samples consisting only of participants seeking or receiving mental health treatment were excluded. Main analyses involved pooled incidence estimates and meta-analyses of variance. RESULTS The overall rate of PTSD was 15.9% (95% CI 11.5-21.5), which varied according to the type of trauma and gender. Least at risk were boys exposed to non-interpersonal trauma (8.4%, 95% CI 4.7-14.5), whereas girls exposed to interpersonal trauma showed the highest rate (32.9%, 95% CI 19.8-49.3). No significant difference was found for the choice of assessment interview or the informant of the assessment. CONCLUSIONS Research conducted with the best available assessment instruments shows that a significant minority of children and adolescents develop PTSD after trauma exposure, with those exposed to interpersonal trauma and girls at particular risk. The estimates provide a benchmark for DSM-5 and ICD-11.

Is trait resilience characterized by specific patterns of attentional bias to emotional stimuli and attentional control? J Behav Ther Exp Psychiatry 2015; 48:133-9. [PMID: 25863483 DOI: 10.1016/j.jbtep.2015.03.010] [Citation(s) in RCA: 19] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/19/2014] [Revised: 03/04/2015] [Accepted: 03/20/2015] [Indexed: 11/16/2022]
Abstract
BACKGROUND AND OBJECTIVES Attentional processes have been suggested to play a crucial role in resilience defined as positive adaptation facing adversity. However, research is lacking on associations between attentional biases to positive and threat-related stimuli, attentional control and trait resilience. METHODS Data stem from the follow-up assessment of a longitudinal study investigating mental health and related factors among German soldiers. Trait resilience was assessed with the Connor-Davidson Resilience Scale and attentional control with the Attentional Control Scale. A subset of n = 198 soldiers also completed a dot probe task with happy, neutral and threatening faces. RESULTS Attentional control was positively related to trait resilience. Results revealed no associations between both attentional biases and trait resilience. However, there was a negative association between attentional bias to threat and trait resilience when attentional control was low and a positive association between attentional bias to threat and trait resilience when attentional control was high. No such associations were found for attentional bias to positive stimuli. LIMITATIONS Generalizability to other populations may be limited since we exclusively focused on male soldiers. Also, the cross-sectional design does not allow for causal conclusions. CONCLUSIONS Findings suggest that attentional processing may promote trait resilience. Future research on preventive interventions should consider these findings.

Hair cortisol concentrations and cortisol stress reactivity predict PTSD symptom increase after trauma exposure during military deployment. Psychoneuroendocrinology 2015; 59:123-33. [PMID: 26072152 DOI: 10.1016/j.psyneuen.2015.05.007] [Citation(s) in RCA: 103] [Impact Index Per Article: 11.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/27/2015] [Revised: 04/24/2015] [Accepted: 05/12/2015] [Indexed: 10/23/2022]
Abstract
BACKGROUND Previous evidence on endocrine risk markers for posttraumatic stress disorder (PTSD) has been inconclusive. Here, we report results of the first prospective study to investigate whether long-term hair cortisol levels and experimentally-induced cortisol stress reactivity are predictive of the development of PTSD symptomatology in response to trauma during military deployment. METHODS Male soldiers were examined before deployment to Afghanistan and at a 12-month post-deployment follow-up using dimensional measures for psychopathological symptoms. The predictive value of baseline (i) hair cortisol concentrations (HCC, N=90) and (ii) salivary cortisol stress reactivity (measured by the Trier Social Stress Test, N=80) for the development of PTSD symptomatology after being exposed to new-onset traumatic events was analyzed. RESULTS Baseline cortisol activity significantly predicted PTSD symptom change from baseline to follow-up upon trauma exposure. Specifically, our results consistently revealed that lower HCC and lower cortisol stress reactivity were predictive of a greater increase in PTSD symptomatology in soldiers who had experienced new-onset traumatic events (explaining 5% and 10.3% of variance, respectively). Longitudinal analyses revealed an increase in HCC from baseline to follow-up and a trend for a negative relationship between HCC changes and the number of new-onset traumatic events. Additional pre-deployment analyses revealed that trauma history was reflected in lower HCC (at trend level) and that HCC were negatively related to stressful load. CONCLUSIONS Our data indicate that attenuated cortisol secretion is a risk marker for subsequent development of PTSD symptomatology upon trauma exposure. Future studies are needed to confirm our findings in other samples.

Stress exposure and the risk for the onset of alcohol use disorders and nicotine dependence in deployed military personnel: the role of prior internalizing disorders. Addict Behav 2015; 43:89-96. [PMID: 25588794 DOI: 10.1016/j.addbeh.2014.12.013] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/01/2014] [Revised: 12/04/2014] [Accepted: 12/18/2014] [Indexed: 11/25/2022]
Abstract
OBJECTIVE This prospective study aimed to investigate whether prior internalizing disorders (PIDs) moderate the relationship between stress exposure (SE) and the onset of alcohol use disorders (AUDs) and nicotine dependence (ND) in deployed military personnel. METHODS 358 male soldiers were examined directly before and 12months after return from deployment using standardized interviews. Combat experiences, concerns about family disruptions, and difficult living and working environment were assessed as different aspects of SE. PID diagnoses (mood disorders (PMDs), anxiety disorders (PADs)) and substance use disorders were defined according to the DSM-IV-TR. RESULTS PMDs were related to a stronger association between concerns about family disruptions and the risk of AUD onset (OR=7.7, 95% CI 1.8-32.8, p=0.006). The number of PID diagnoses (OR per diagnosis: 1.7, 95% CI 1.0-2.8, p=0.036) and PADs (OR: 2.6, 95% CI 1.1-6.3, p=0.038) were further related to a stronger association between difficult living and working environment and the risk of AUD onset. With regard to ND, PMDs were related to a weaker association between difficult living and working environment and the risk of ND onset (OR=0.4, 95% CI 0.2-0.8, p=0.013). CONCLUSIONS PIDs might be related to an increased risk for the onset of AUDs but not ND following SE. This effect is probably restricted to specific constellations of PADs, PMDs, comorbid PIDs and specific aspects of SE. These critical constellations of PIDs and SE might be a promising target for future research and could contribute to the development of preventive measures to reduce the risk of AUDs following SE.

[PMID: 25499731 DOI: 10.1016/j.drugalcdep.2014.11.019] [Citation(s) in RCA: 20] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/01/2014] [Revised: 10/22/2014] [Accepted: 11/21/2014] [Indexed: 11/26/2022]
Abstract
BACKGROUND Several studies have documented factors related to increase in alcohol consumption in the context of stressful experiences. However, little is known about predictors of different courses of alcohol use in this context. This study aims to investigate diverse predictors and correlates of increase and decrease of average daily alcohol consumption (aDAC) in the aftermath of military deployment taking into account a variety of potentially relevant factors. METHODS N=358 soldiers were examined before (T1) and 12 months after return from deployment (T2) using standardized interviews. Change in aDAC was categorized into decreased (n=72), stable (n=215) and increased (n=71) aDAC. RESULTS Overall, aDAC did not change significantly between T1 and T2 (median change=0.0 g, inter quartile range=11.3g). Compared to stable aDAC, increase was characterized by a lower proportion of high-educated individuals (OR: 0.3 (0.1-0.7), p=0.008), lower rank (marginally significant: OR: 2.0 (1.0-4.1), p=0.050), and less acceptance (trend: MR: 0.97 (0.93-1.00), p=0.053). Correlates of increased aDAC were less social support (MR: 0.84 (0.71-0.99), p=0.043), more sleeping problems (MR: 1.15 (1.00-1.31), p=0.045) and more negative post-event cognitions following deployment (MR: 2.32 (1.28-4.21), p=0.006). Decrease in aDAC was predicted by lower PTSD symptom severity before deployment (MR: 0.34 (0.16-0.72), p=0.005) and less childhood emotional neglect (marginally significant: MR: 0.78 (0.60-1.00), p=0.050). CONCLUSIONS Increase and decrease in alcohol use after stressful experiences might have differential risk factors and correlates. Findings might stimulate future research that could result in improved measures to prevent increases as well as in interventions that could foster decreases in alcohol consumption in the context of stressful experiences.

Abstract
This paper aimed to extend the existing knowledge on the association between PTSD symptoms, alcohol use disorders (AUD) and nicotine dependence (ND) by distinguishing between anxious and dysphoric arousal PTSD symptoms and by considering the putative contribution of additional comorbidity. Data stem from a cross-sectional study in a stratified, representative sample of 1483 recently deployed soldiers using standardized diagnostic interviews. All lifetime PTSD symptom clusters (occurrence of any symptom and number of symptoms) were associated with current AUD and ND in crude models except that anxious arousal was not related to AUD. Associations were reduced in magnitude when controlling for comorbidity. Current ND was related to the occurrence of any emotional numbing and to the number of re-experiencing symptoms above the contribution of other symptom clusters and comorbidity. In conclusion, associations between PTSD symptoms, AUD and ND may be partially attributable to additional comorbidity. Findings also yield further evidence for a role of emotional numbing and re-experiencing symptoms in the comorbidity between PTSD and ND and for a distinction between dysphoric and anxious arousal PTSD symptoms.

Abstract
BACKGROUND For years there has been a tremendous gap in our understanding of the mental health effects of deployment and the efforts by military forces at trying to minimize or mitigate these. Many military forces have recently systematized the mental support that is provided to support operational deployments. However, the rationale for doing so and the consequential allocation of resources are felt to vary considerably across North Atlantic Treaty Organisation (NATO) International Security Assistance (ISAF) partners. This review aims to compare the organization and practice of mental support by five partnering countries in the recent deployment in Afghanistan in order to identify and compare the key methods and structures for delivering mental health support, describe bottlenecks and illustrate new developments. METHOD Information was collected through document analysis and semi-structured interviews with key military mental healthcare stakeholders. The review resulted from close collaboration between key military mental healthcare professionals within the Australian Defense Forces (ADF), Canadian Armed Forces (CAF), United Kingdom Armed Forces (UK), Netherlands Armed Forces (NLD), and the United States Army (US). Key stakeholders were interviewed about the mental health support provided during a serviceperson's military career. The main items discussed were training, prevention, early identification, intervention, and aftercare in the field of mental health. RESULTS All forces reported that much attention was paid to mental health during the individual's military career, including deployment. In doing so there was much overlap between the rationale and applied methods. The main method of providing support was through training and education. The educative focus was to strengthen the mental resilience of individual soldiers while providing a range of mental healthcare services. All forces had abandoned standard psychological debriefing after critical incidents. Instead, by default, mental healthcare professionals acted to support the leader and peer led "after action" reviews. All countries provided professional mental support close to the front line, aimed at early detection and early return to normal activities within the unit. All countries deployed a mental health support team that consisted of a range of mental health staff including psychiatrists, psychologists, social workers, mental health nurses, and chaplains. There was no overall consensus in the allocation of mental health disciplines in theatre. All countries (except the US) provided troops with a third location decompression (TLD) stop after deployment, which aimed to recognize what the deployed units had been through and to prepare them for transition home. The US conducted in-garrison 'decompression', or 'reintegration training' in the US, with a similiar focus to TLD. All had a reasonably comparable infrastructure in the field of mental healthcare. Shared bottlenecks across countries included perceived stigma and barriers to care around mental health problems as well as the need for improving the awareness and recognition of mental health problems among service members. CONCLUSION This analysis demonstrated that in all five partners state-of-the-art preventative mental healthcare was included in the last deployment in Afghanistan, including a positive approach towards strengthening the mental resilience, a focus on self-regulatory skills and self-empowerment, and several initiatives that were well-integrated in a military context. These initiatives were partly/completely implemented by the military/colleagues/supervisors and applicable during several phases of the deployment cycle. Important new developments in operational mental health support are recognition of the role of social leadership and enhancement of operational peer support. This requires awareness of mental problems that will contribute to reduction of the barriers to care in case of problems. Finally, comparing mental health support services across countries can contribute to optimal preparation for the challenges of military deployment.

Abstract
International studies suggest a growing risk of posttraumatic stress disorder (PTSD) with an increasing duration of deployment. There are no data available for the German armed forces that would allow an assessment of the average mission duration of about 4 months. Analyses are based on a stratified random sample of 1,483 ISAF soldiers. Standardized diagnostic interviews were conducted about 12 months after soldiers returned from mission. Deployment duration was categorized into 1-2 months, 3-5 months, and 5-8 months. Additionally, dimensional analyses of deployment duration were performed. Deployment duration was associated with the number of stressful and traumatic events. Notwithstanding, we found no linear relationship between mission duration and PTSD risk, neither in the total sample nor in the defined subgroups. However, we found a bimodal distribution suggesting an increased PTSD risk in the first 2 months and - less pronounced and limited to the Kunduz location - for deployment durations of at least 6 months. There was no general increase in PTSD risk with increasing deployment durations for German soldiers in this naturalistic study. The higher risk for soldiers with short deployments might be explained by selection of vulnerable subjects and different deployment characteristics. Further, there is some evidence of an increased PTSD risk for soldiers deployed for longer periods to high-risk locations (e.g., Kunduz).

Abstract
BACKGROUND Military studies investigating the prevalence of substance use (SU) and substance use disorders (SUD) and the relation between SU and mental disorders often lack a comprehensive assessment of SU, SUD and mental disorders and comparable groups of deployed and non-deployed personnel. There is also limited data regarding SU and SUD in the German military to date. METHODS Cross-sectional examination of n=1483 soldiers recently deployed in Afghanistan and 889 never deployed soldiers using a fully-standardized diagnostic interview (MI-CIDI) including a comprehensive substance section. RESULTS Across both groups, 12-months prevalence of DSM-IV alcohol use disorders was 3.1%, 36.9% reported binge drinking, 13.9% heavy drinking, 1.3% illegal drug use. 55.1% were regular smokers, 10.9% nicotine dependent. Although recently deployed soldiers revealed slightly higher rates in some measures, there were no significant differences to the never deployed regarding SU und SUD except that recently deployed soldiers smoked more cigarettes per day. The association of SU with mental mental disorders was substantially different though, revealing significant associations between SU and mental disorders only among recently deployed soldiers. CONCLUSIONS We do not find remarkable differences in the prevalence of SU and SUD between recently deployed and never deployed soldiers. Especially binge drinking and regular smoking were prevalent across both samples indicating needs for improved interventions. The finding that SU and mental disorders are only associated in recently deployed soldiers might have implications for improved screening and prevention and suggests that deployment might promote different pathways and mechanisms involved in the evolution of SU and mental disorders.

Abstract
BACKGROUND Little is known about the frequency of traumatic event exposure and the development of post-traumatic stress disorder (PTSD) among German soldiers serving in Afghanistan. METHODS We studied a random sample consisting of 1599 soldiers who had served in the 2009/2010 ISAF mission in Afghanistan, stratified by deployment location and unit. Twelve months after their return to Germany, the soldiers were assessed with a Composite International Diagnostic Interview (CIDI) to establish the diagnoses of mental disorders and PTSD according to the DSM-IV. 889 similar soldiers who had not been deployed abroad were assessed in the same way. RESULTS 49.2% (95% confidence interval [CI]: 46.4 to 52.1) of the deployed soldiers experienced at least one traumatic event during their deployment, and 13% experienced more than three. The 12-month prevalence of PTSD among returning soldiers was 2.9% (95% CI: 2.1 to 4.1), while the service-related incidence after deployment was 0.9% (95% CI: 0.5 to 1.6). These figures imply a two- to fourfold elevation of the risk of PTSD. The risk of PTSD was highest among soldiers who had served in Kunduz (Afghanistan) and in combat units. Only half of all soldiers with PTSD sought professional help. CONCLUSION Deployment abroad is associated with a high frequency of traumatic experiences and a two- to fourfold elevation of the risk of PTSD. Each year, about 300 cases of PTSD develop for every 10 000 soldiers who return to Germany; thus, the cumulative number of returnees with PTSD from the beginning of German deployment abroad may currently run into the thousands. 45% of all PTSD cases, or about one in two, are neither diagnosed nor treated. Deployment abroad also substantially increases the risk of developing a number of other mental disorders.
